vpn – OpenVPN error – no path to host?

I’ve 1 inner community and 1 exterior community (public ip enabled). I wish to direct the site visitors from my exterior community to my inner community utilizing reverse proxy and ip routing. I am utilizing openvpn for my inner community. My configuration labored for a while however now it exhibits me error – learn UDPv4 [EHOSTUNREACH]: No path to host (fd=5,code=113).
My server configuration is –

port 1194
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh.pem
native 
server 10.8.0.0 255.255.255.0

cipher AES-256-CBC
consumer no one
group nogroup

my consumer configuration is –

IPtables on the server are –

Chain INPUT (coverage ACCEPT)
goal     prot decide supply               vacation spot

Chain OUTPUT (coverage ACCEPT)
goal     prot decide supply               vacation spot

Journalctl for openvpn on server and consumer don’t have any errors.
how do I guarantee correct connectivity between the networks?
